The Schneider NSX 100F MA2.5A is a 3-pole molded case circuit breaker (MCCB) from the NSX series, designed for overload and short-circuit protection in industrial and commercial electrical systems.
Specifications:
Type: Molded Case Circuit Breaker (MCCB)
Number of Poles: 3P (3 poles) – Suitable for three-phase systems
Current Rating: 100A
Frame Size: 100F (denotes the frame size for medium-current protection applications)
Rated Voltage: Typically 415V (for three-phase systems)
Rated Frequency: 50/60 Hz
Magnetic Protection Setting: MA2.5A (adjustable short-circuit protection set to 2.5 times the rated current)
Thermal Protection: Adjustable thermal protection for overload conditions.
Tripping Characteristics:
Thermal Protection: Provides protection against prolonged overload conditions by tripping after a specific time when the current exceeds the rated value.
Adjustable Magnetic Trip: The magnetic trip is adjustable to 2.5 times the rated current, offering flexibility in short-circuit protection. This ensures that the breaker can handle inrush currents or other temporary surges without tripping unnecessarily, while still offering protection against sustained short-circuits.
Instantaneous Magnetic Protection: Provides quick disconnection in the event of a short circuit, ensuring that no further damage occurs to the system.
Breaking Capacity: Typically 25 kA at 415V (maximum fault current the breaker can safely interrupt)
Protection Features:
Overload Protection: Disconnects the circuit when the current exceeds the rated value for an extended period, preventing the circuit from overheating and ensuring the safety of wiring and connected equipment.
Short-Circuit Protection: Disconnects the circuit instantaneously in the event of a short circuit, preventing extensive damage to the electrical components and infrastructure.
Manual Reset: The breaker can be manually reset once it has tripped, after the fault has been cleared, to restore normal operation.
